Nua has been around the longest. He spent 2005 and 2006 on the Pittsburgh Steelers practice squad and last year was on the Bills practice squad for the final five games.

Baker's release means Gibran Hamdan likely will remain the No. 3 QB unless the Bills decide to start the season with only two, as they did last year. But given the injury histories of Trent Edwards and J.P. Losman, Hamdan probably is safe.
